The [Kisai Keisan](https://www.trendhunter.com/trends/gav01-series) has a curvy frame and uses a rippled convex lens that magnifies the lighting effect from the LEDs behind the numbers in the watch face. Although this timepiece may take a bit of time to get used to compared to some of the [other watches in the Tokyoflash line](https://www.trendhunter.com/trends/casio-aq240e3a), getting the hang of the Kisai is fairly simple. To reveal the time or date, simply add the numbers vertically in the columns of each of the [four rows](https://www.trendhunter.com/trends/triaxial-numechron-clock). These retail for approximately $225 USD and can be bought online from the Tokyoflash website. ## Trend Insights (Trend Hunter) - Score: 1.8/10 - Popularity: 24% | Activity: 23% | Freshness: 8% - Audience gender: 10% men, 90% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Fashion](https://www.trendhunter.com/fashion) > [Watches](https://www.trendhunter.com/watches) ## Key Themes ### Key Themes Behind This Trend - **Abacus-inspired Watches:** Disruptive innovation opportunity: Designing watches that use unconventional methods to tell time, creating unique and eye-catching timepieces. - **Easy-to-read Watches:** Disruptive innovation opportunity: Developing watches with innovative designs that prioritize readability, making it quick and effortless for users to tell the time. - **Magnifying Effects in Watch Design:** Disruptive innovation opportunity: Implementing magnifying technologies in watch designs to enhance the visibility and legibility of the time display, providing a clearer and more user-friendly experience. ### Where This Applies - **Watch Manufacturing:** Disruptive innovation opportunity: Exploring new and creative designs in watch manufacturing, appealing to customers who seek unique and unconventional timepieces. - **Technology and Wearables:** Disruptive innovation opportunity: Integrating advanced technologies into watches, enhancing functionalities and offering new ways of interaction for users. - **E-commerce and Retail:** Disruptive innovation opportunity: Embracing the online retail landscape and creating a seamless shopping experience for customers, allowing them to easily purchase innovative watches like those from Tokyoflash. ## Related on Trend Hunter - [Rock-Textured Field Watches](https://www.trendhunter.com/trends/kiwame-tokyo-iwao-sumi.md) - [Perplexing Artistic Timepieces](https://www.trendhunter.com/trends/otsuka-lotec-no5-kai.md) - [Japan-Inspired Wearable Watch Rings](https://www.trendhunter.com/trends/stasto-stand-stones.md) - [Open-Concept Retro-Style Timepieces](https://www.trendhunter.com/trends/amida-digitrend-open-sapphire.md) - [Large Watch-Style Alarm Clocks](https://www.trendhunter.com/trends/casio-japan.md) - [Zen Garden-Inspired Timepieces](https://www.trendhunter.com/trends/japanese-zen-garden.md) - [Japanese Woodwork-Inspired Watch Designs](https://www.trendhunter.com/trends/japanese-woodwork.md) - [Angular Automobile-Inspired Timepieces](https://www.trendhunter.com/trends/benly-design-s3000-cyber-watch.md) - [Origami-Inspired Watches](https://www.trendhunter.com/trends/casio-31.md)
